Western SARE
WSARE | 2021 | 2 pages

Most agricultural soils in Montana are not naturally acidic. However, crop losses due to increasing soil acidification have now occurred in 24 Montana counties.

In Idaho, for example, ag soils went from neutral to significantly acidic in about 25 years. This quick guide provides tips on how to prevent acidification.
